For both [Havelock] Ellis and Jeffers, insane mainkind would
go down before the lasting grandeur of Nature. The restorative
power of Nature, to which all things transitory and human
eventually return, is described by Jeffers in November Srf.
Considering the respective dates of composition and the
correspondent attitudes toward Nature's regenerative capacity to
absorb humanity's decay and contamination, it is not unreasonable
to suggest that the poem owes a debt to the following passage
from Ellis' Fountain of Life:

Alone but for a few meditative gulls, I sit among the
rocks and dream of the miracle of this restless, antiseptic
sea that for millions of years has been slowly and tirelessly
absorbing all the rejected filth that the Earth and now Man
can pour into it, and still to-day, as at the first, sends
forth its fresh procession of waves in Purity and Joy, for
the sacred lustration of an Evil World.

From Ellis' various statements, then, Jeffers apparently could
have drawn considerable inspiration. Ellis had no fully developed
philosophical system of his own from which Jeffers could borrow,
but the men were emotionally compatible in their regard for
Nature, they shared theories about the cycles of civilization,
they recognized certain possibilities in Nietzsche's philosophy,
they were equally concerned about the interrelationship of
morality and art, and, though they differed somewhat on the role
of science, their ideas of truth were all but identical.
